As of 2015, shoppers can buy an aftermarket Family Care FCF620 Humidifier Filter from online shops such as Amazon, US Home Filter, Filters Fast and Walmart. This aftermarket filter fits a range of Family Care humidifiers including models from the HM and WWHM series.
The Family Care FCF620 humidifier filter prevents the growth and movement of mold, fungi, algae and bacteria. The filter traps these microscopic pollutants from the water in the humidifier, and it prevents them from getting into the air surrounding the humidifier.
In addition to keeping the air in a home clean, filters ensure the optimum performance of the humidifier, and ideally, they should be replaced every two months or at the beginning of the humidifier season. However, actual replacement times vary based on how much the humidifier is being used.
As of 2015, FCF620 humidifier filters are sold in packs of one or two, and the shipping weight for two filters is 3 pounds. Filters come with instructions detailing how to install them in humidifiers.
These white colored filters use a honeycomb filtration system to remove pollutants from the water in the humidifier, and the filters feature antimicrobial agents to boost how well they work on bacterial pollutants.
